Just in time for the PlayStation Vita's launch in Japan this weekend, Sony has revealed in-depth details about the console by releasing the console's digital user manual.

The console won't be reaching the U.S. and European markets until February 22nd. But the digital user manual is available in English, giving customers plenty of reading up before they pre-order.

Sony announced on Thursday that the PlayStation Vita has already sold out on pre-orders in Japan. With big queues at the 'testing booths' they posted in Tokyo last weekend, interest in the Vita in Japan is high.

The manual reveals details on user accounts, trophies, charge time and backwards compatibility.

Some of the key details are:

As they stated on Thursday, the console will be one account per console. Memory cards will be linked to PlayStation Network accounts, but you can only use memory cards in Vita systems to which the account is attached.

Vita owners would have to delete all of their data and reset factory settings in order to sign in with a different account.
